Hi,
As a result of trying to help Lee out on his MX problem, I tried a few experiments. The LX screens do fit the MX and they are brighter. Using the SC21 (standard LX screen) results in a much brighter finder with crisper microprisms but you need to compensate by 2/3 to 1 stop on the metering. The good news is that if anyone wants an even brighter still MX finder the 2000 LX screens will fit. I suspect they will need about 2 stops compensation but the cost would only be about a 1/3 of that of a Beattie screen.

Hi Kim

It may be that not all the screens will fit - I think I have the info somewhere, I'll check.
Best regards, John

Hi John,
They all appear to be the same size physically and Pentax say that all the MX screens fit the LX. I tried the standard SC21, the all matt SE20 and SE25 and a couple of SA series in the MX. I would have tried the SC69 bright screen but I didn't want to take the LX apart as well. If anyone is desperate for the info I will try it but it's a devil to get the screens back in without trapping any dust. I know it doesn't affect the photo but I find it distracting.

As a matter of interest, the AF screens also appear to be the same size and interchangeable. I far as I can tell the only difference between the various series is the markings for the AF zones. The SF ones fit the Z1P and vice versa but I haven't tried with the MZ-S. This could be useful if someone wants a manual focus aid in an AF camera.
